looking imposter. No agreement between perceptual recognition and the
emotional response, creates a sense that they are not loved ones. Often from
prefrontal cortex damage which impairs reasoning
all-or-none law principle that the action potential in a neuron does not vary in strength; the
neuron either fires at full strength or it does not fire at all
action potential a signal that moves down its axon, which in turn causes the release of
neurotransmitters at the next synapse, potentially causing the next cell to fire.
synapse the junction between the axon tip of the sending neuron and the dendrite or
cell body of the receiving neuron
presynaptic membrane the specialized membrane on the axon terminal of a nerve cell that transmits
information by releasing neurotransmitter
postsynaptic membrane the cell membrane opposite the terminal button in a synapse; the membrane
of the cell that receives the message
